Dunstable Sailplane Company
The Dunstable Sailplane Company was established in 1934 by W.L. Manuel and C.H. Latimer-Needham to design, manufacture and repair gliders from its workshop at Barton-Le-Clay Airfield in Bedfordshire, UK.
The Dunstable Kestrel was manufactured by the company from designs by W.L. Manuel in 1935; production was limited to one sailplane with a British Gliding Association id of G221.
W.L. Manuel drew up plans for home builders which were offered for sale at the cost of £6. 6s.
W. L. Manuel was born William Lancelot Manuel in 1903; parish records list his birthplace as Malling, Kent. Manuel spent his early life working at RAF Hawkinge Kent with 25 Fighter Squadron, He was a key member in the establishment of the Channel Gliding Club (1930), and built an estimated 14 aircraft over his 84-year life. William Manuel retired in 1965 from the AC Cars company of Thames Ditton; it is thought he was the company’s chief planning engineer on retirement.
